圆钢是指截面为圆形的实心长条钢材。其规格以直径的毫米数表示，如“ 50”即表示直径为 50毫米的圆钢。
圆钢与其它钢筋的区别:1 外型不一样,圆钢外型光园,无纹无肋,其它钢筋表面外型有刻纹或有肋.这样就造成圆钢与混凝土的粘结力小,而其它钢筋与混凝土的粘结力大. 2 成份不一样,圆钢(一级钢)属于普通低碳钢,其它钢筋多为合金钢. 3 强度不一样.圆钢强度低,其它钢强度高,即直径大小相同的圆钢与其它钢筋相比,圆钢所能承受的拉力要比其它钢筋小,但圆钢的塑性比其它钢筋强,即圆钢在被拉断前有较大的变形,而其它钢筋在被拉断前的变形要小得多。
Forged round is a round steel that has been forged by the process. Specifications domestic general production can reach 1500mm diameter. Forgings are forged and impact, suitable for small parts or profiled steel.
Round steel is mostly supplied in straight strips, often used as steel bars, bolts and various mechanical parts; round steels larger than 25 mm are mainly used for manufacturing mechanical parts or seamless steel tube blanks.
Round steel is a solid strip of steel with a circular cross section. The specifications are expressed in millimeters of diameter. For example, "50" means a round steel with a diameter of 50 mm.
Round steel is divided into hot rolling, forging and cold drawing. Hot rolled round bars are available in sizes from 5.5 to 250 mm. Among them: small round steels of 5.5-25 mm are mostly supplied in straight strips, often used as steel bars, bolts and various mechanical parts; round steels larger than 25 mm are mainly used for manufacturing mechanical parts or seamless steel tube blanks.
The difference between round steel and other steel bars: 1 The shape is different, the round steel shape light garden, no grain and no ribs, the other steel surface has a pattern or ribs on the surface. This results in a small bond between the steel and the concrete. The other steel bars have a strong adhesion to concrete. 2 The composition is different. The round steel (first grade steel) belongs to ordinary low carbon steel, and the other steel bars are mostly alloy steel. 3 The strength is different. The round steel has low strength and other steel strength. High, that is, round steel of the same diameter, compared with other steel bars, the round steel can withstand less tensile force than other steel bars, but the round steel is more plastic than other steel bars, that is, the round steel has a larger before being pulled off. Deformation, while other steel bars are much less deformed before being pulled off.
